RE: RDF to HTML with XSLT

From: JasonBurr@-----------.---------.---

Date: 1/7/2005 1:31:00 PM
Thanks everyone who pitched in to help me. I went back to some code I wrote a 
while back that was a lot cleaner (for postal api's) and started from scratch 
this seems to work just fine. This does not however end the issue as I have 
the same problem on client side code and suspect it has to do more with which 
xml object versions are being used. Anyway for anyone who may have looked at 
this and wanted to know the solution here it is

Response.Buffer = True
Response.charset = "utf-8"

strXMLOut="<?xml version=""1.0"" encoding=""utf-8""?>" &_
"<rdf:RDF" &_
"        xmlns:rdf = ""http://www.w3.org/1999/02/22-rdf-syntax-ns#"" " &_
"        xmlns:dc  = ""http://purl.org/dc/elements/1.1/"" " &_
"        xmlns:mq  = ""http://musicbrainz.org/mm/mq-1.1#"" " &_
"        xmlns:mm  = ""http://musicbrainz.org/mm/mm-2.1#"">" &_
"<mq:FindArtist>" &_
"  <mq:depth>4</mq:depth>" &_
"  <mq:artistName>Portishead</mq:artistName>" &_
"</mq:FindArtist>" &_
"</rdf:RDF>"

strUrl = "http://www.musicbrainz.org/cgi-bin/mq_2_1.pl"

strXSLPath = Server.MapPath("music.xsl")

Set xmlDoc = Server.CreateObject("MSXML.DOMDocument")
Set xmlhttp = Server.CreateObject("Msxml2.ServerXMLHTTP.3.0")  
xmlhttp.open "POST", strUrl, false 
xmlhttp.send strXMLOut 

strXMLReturn = xmlhttp.responseText
xmlDoc.validateOnParse = False
xmlDoc.loadXML(strXMLReturn)

Set xmlhttp = Nothing

'Load the XML.
Set source = Server.CreateObject("MSXML2.DOMDocument.3.0")
source.async = false
source.resolveExternals = false
source.load(xmlDoc)

'Load the XSLT.
Set style = Server.CreateObject("MSXML2.DOMDocument.3.0")
style.async = false
style.resolveExternals = false
style.load(strXSLPath)
strOutPut = source.transformNode(style)

Response.Write strOutPut

Set xmlDoc = Nothing
Set source = Nothing
Set style = Nothing
